[coreboot] [PATCH]RCA RM4100 and Thomson IP1000 auto.c rework

[Joseph Smith]

Hello,
This is a rework patch for the RCA RM4100 and Thomson IP1000. A few of 
the changes include:

1. Setting up the PCI Host Bridge registers (not doing this was causing 
random unexpected exception errors)

2. Setting up some LPC registers

3. dropping the early lpc code to disable the TCO timer. This probably 
can also be dropped from the i82801xx code too. To my suprise the is an 
LPC register that disables this completely (0xd4).

4. move gpio code to run earlier.

5. all this needs to be done pre-raminit

Build and Run tested. See patch.
